3HAC022032-001 Revision: Q
WARNING
If the air pressure exceeds the specified, it could result in a brake failure in the
motors and cause the robot arms to fall down, leding to personal injure or physical
damage.
Note
To secure sufficient air pressure, it is recommended to use a pressure sensor.
WARNING
The robot must be pressurized also when it is switch off, to avoid that the humid
environmental air is sucked into the motors when cooling down.
Action
Connect a compressed air hose to air con-
nector on robot base, see illustration.
Protect the screws on the Harting connectors
on the robot base from corrosion with Mer-
casol.
Pressurize the robot.
Inspect the air system.
WARNING
No part of the robot are allowed to be exposed to direct high pressure jet of water.
The sealings between the moving parts on the wrist must not be exposed to
direct or rebounding high-pressure jet of water.
